Rent NowThe Canon RF 28mm f/2.8 STM Lens is a sleek, bright wide-angle pancake prime designed for Canon’s full-frame RF-mount mirrorless cameras, offering an exceptionally compact and affordable entry point into Canon’s RF system. It’s well suited to travel, street photography, and video, with a classic wide-angle field of view and close-focusing capability for everyday, walkaround shooting.
Optically, the lens offers a 28mm focal length (75-degree angle of view, approximately 45mm equivalent on APS-C bodies) with a maximum aperture of f/2.8 narrowing to f/22. The 8-element, 6-group optical design includes three precision-molded aspherical elements to combat spherical aberrations and distortion for accurate, sharp rendering, along with Canon’s Super Spectra Coating to boost contrast and color neutrality while minimizing ghosting and flare. A rounded 7-blade diaphragm contributes to pleasing bokeh, and the lens is capable of producing distinctive sunstars when stopped down to f/22.
Autofocus is handled by a gear-type STM (stepping motor), delivering fast, quiet, smooth, and accurate performance well suited to both stills and video recording, with full-time manual focus override via Quick-Shift AF, letting photographers simply rotate the focus ring to switch to manual focus at any time. The lens also includes a customizable control ring for adjusting settings like ISO, aperture, or exposure compensation directly from the barrel, along with an AF/MF switch. A standout feature is the lens’s close-focusing capability, with a minimum focusing distance of just 0.23m (9.1 in.), yielding a maximum magnification of 0.17x (1:5.9).
Build quality centers on an ultra-compact pancake design, retracting to a parked position with the inner barrel flush with the outer barrel when the camera is powered off. It measures approximately 69.2 x 24.7mm, among the shortest lenses Canon has produced, and weighs just 120g (4.2 oz.), making it easy to carry everywhere. It accepts a 55mm filter thread and is not weather- or dust-sealed, and does not include image stabilization or compatibility with Canon’s extenders.
As a full-frame RF-mount lens, the RF 28mm f/2.8 STM delivers its full angle of view on Canon full-frame RF-mount bodies while remaining compatible with Canon APS-C RF-mount cameras at a narrower, telephoto-equivalent effective field of view.
